ON ROSA POLYANTHA AS A STOCK FOR BUDDING. 
BY M. VIVIAND MOREL, LYONS. 
The author points out that M. Alegatiere, of Lyons, ascertained that 
the seeds of this species germinate within a month without being strati¬ 
fied, so that the stock can be budded in the first year. Various con¬ 
firmatory statements by different experimenters are given ; amongst 
•others, some by M. Bernaix, who advocates the budding of Boses on 
■seedling Polyantha stocks as specially suitable for pot Roses, and Roses 
intended for forcing. Such plants come into growth and flower ten to 
fifteen days earlier than those budded on the Briar, and do not throw 
up suckers. The stock is as well suited for Teas as for H.P.’s. 
M. Viviand Morel himself repeated these experiments with the same 
Tesults. 
A comparative trial of Roses for forcing, budded on the seedling 
Polyantha and on the seedling Briar respectively, and in which the 
•conditions were identical, gave the following results :—Roses budded on 
the Polyantha stock gave twice the number of flowers that the same 
variety produced on the Briar, and, further, they were a fortnight 
•earlier. 
The Dinner. —In the evening between sixty and seventy gentle" 
men, Fellows of the Society and members of the National Rose Society; 
Hined together at the Hotel Mdtropole, under the chairmanship of Sir 
Trevor Lawrence, Bart., M.P., President of the Royal Horticultural 
■Society, who was supported on the right by the Very Reverend the Dean 
of Rochester, M. de la Devansaye, and Dr. Hogg, and on the left by 
Mr. J. G. Baker and Dr. Masters. The Dean of Rochester proposed 
■“ Prosperity to the National Rose Society,” coupled with the name of 
’Rev. H. H. D’Ombrain, the Secretary. Then followed the health of the 
•“President of the Royal Horticultural Society,” “ The Visitors,” re- 
•sponded to by M. de la Devansaye ; “ The Press,” which was responded 
do by Dr. Master, Dr. Hogg, and Mr. Shirley Hibberd.

FRUIT FORCING. 
Vines. — Early Houses. —The Grapes having been cut, keep the 
house as cool as possible by free ventilation, and withdraw the roof 
lights where practicable when rains prevail. The cleansing effect of 
Tain is very beneficial, and a thorough moistening of the borders will do 
much towards the production of fresh laterals and the maintenance in 
•health of . the principal leaves, thereby preventing premature ripening of 
the foliage. Vines that are becoming exhausted through long subjec¬ 
tion to early forcing and bearing heavy crops should have one of the 
borders renovated, and the roots laid in fresh material near the surface, 
for which prepare by getting the material together, as it is important 
work of this kind be executed at the right time and with despatch. 
-One of the borders only need be operated upon at a time, taking say the 
inside border one year, and following with the outside border the next. 
The proper time to attend to the roots in the case of early Vines is as 
•loon as the foliage gives indications of ripening. Syringe the foliage 
•every evening in fine weather to preserve the leaves in a healthy con- 
•dition as long as possible, for when they die prematurely second growth 
will commence about the time the Vines ought to be pruned and going 
do rest. 
Houses of Ripe Grapes. —Keep the houses cool, and on hot days 
■sprinkle water on the borders and floors, which will be beneficial. 
Moderate moisture will not inj'ure ripe Grapes at this season provided it 
•is not stagnant and the temperature is not allowed to advance in the 
morning before ventilation is increased. A temperature of 55° to 60° 
•will be sufficient for ripe Black Hamburghs at night, but Muscats will 
meed fire heat to prevent the temperature falling below G0° to 65° at 
might. Turning on the heat in the morning to allow a free circulation 
will materially assist in the maturing of Muscats even after they appear 
Tipe. Moisture must be carefully guarded against in the case of 
Muscats, or they soon spot in a moist confined atmosphere. Allow a 
gentle circulation of air constantly, even if fire heat has to be employed 
■to secure it. A slight shade is absolutely essential to Black Hamburghs 
keeping colour for any length of time after ripening. Some doubled 
garden netting drawn over the lights is mostly sufficient. Muscats 
•colour in proportion to the light and heat they receive. 
Grapes Ripening. —Ventilate constantly, a circulation of warm 
■rather dry air being essential to good finish. Black Hamburghs and 
similar varieties need only have a night temperature of 60° to 65°, and 
70° to 75° by day ; but Muscats require 70° to 75° at night, and 80° to 
85° by day, advancing with sun heat to 90° or 95°. If there is likely to 
he any deficiency of moisture in the borders, give a thorough soaking, 
•choosing the early part of a fine day, and ventilate freely. Mulching 
with short dry material will prevent any danger of moisture arising to 
dbe injury of the crop. Admit plenty of air after the Grapes change 
.colour. 
Grapes Stoning. —Dull weather, with occasional gleams of sun is 
the worst for scorching and scalding Grapes. It is best to have a little 
fire heat to prevent a low night temperature, and admit of early venti¬ 
lation to prevent the deposition of moisture upon the berries. If they 
are allowed to be covered with moisture, and the sun raises the tem¬ 
perature considerably before ventilation is given, the leaves and berries 
will assuredly suffer. A little heat and free early ventilation are the 
preventives of scorching and scalding. When the stoning is over, and 
the fruit commences ripening, danger from scalding is considered past, 
but Muscat of Alexandria is often scorched badly even after the Grapes 
are advanced in colour, and a slight shade as that of garden nets 
drawn over the roof lights is of great benefit. 
Late Houses of Blacli Hamburghs. —The thinning must be concluded 
without delay. Thin well, but not unduly, and remove surplus bunches 
if there be any doubt about the crop, for Black Hamburghs to hang 
well must be as thick in the skin, as firm in flesh, and as highly 
finished as possible. It is nonsense expecting crops that do not finish 
higher in colour than a reddish black to hang well, for they will 
only disappoint. Either they must be black and have as much bloom 
as Sloes, or they will not keep colour long. Allow a fair amount of 
lateral growth, as Grapes of this class finish better with a modified 
light, but avoid overcrowding. 
TRADE CATALOGUES RECEIVED.

Bulbs and Tubers. 
Damman & Co., San Giovanni a Teducio, Naples, Italy .—Wholesale

All correspondence should be directed either to “The 
Editor” or to “ The Publisher.” Letters addressed to Dr. 
Hogg or members of the staff often remain unopened un¬ 
avoidably. We request that no one will write privately 
to any of our correspondents, as doing so subjects them to 
unjustifiable trouble and expense. 
Correspondents should not mix up on the same sheet questions 
relating to Gardening and those on Bee subjects, and should 
never send more than two or three questions at once. All 
articles intended for insertion should be written on one side of 
the paper only. We cannot reply to questions through the 
post, and we do not undertake to return rejected communica¬ 
tions. 
Insects (71 J/.).—We cannot undertake to name insects “'caught 
in fields ” without any reference to the crops they attack. 
Twin Cucumbers (W. Bay). —Such examples are neither very 
common nor very rare. We have one or more sent to us every year, 
and now and then three or four at once. Still they are not produced 
by one plant out of a hundred, and cannot be perpetuated by seed or 
cuttings, the jointure being accidental, not constitutional. 
Pelargonium Sport (<9. J. 4‘ Co.). —We regret that in the absence 
of a little gum for sealing the petals, and the want of packing to keep 
them fresh, that the whole were either shaken off or so much curled and 
withered as to render any satisfactory comparison impossible! One 
flower is evidently much richer in oolour than the loose petals of the 
others, and resembles the variety named Dr. Masters. 
Seedling Carnation (//. A. M.). —The flowers arrived in such a 
withered state, through want of suitable packing, that it is impossible 
to determine the merits of the variety. It is as disappointing to us as 
it must be to the senders of flowers for our opinion, or naming, to find 
that they arrive in what must be a totally different condition from that 
in which they were when gathered. It is essential that they reach us 
in a fresh state, as is almost invariably the case when packed according 
to our standing instructions below. 
Gall on Poplars (T. L., Canterbury). —The twigs of Poplar sent 
are to some extent infested with aphides, but the curious galls or pro¬ 
tuberances are the work of a species of Psylla, specimens of whieh in an 
adult stage are crawling about the leaves. Many of the Psyllidae are 
mistaken for aphides, and they are nearly related ; but a Psylla leaps in 
its perfect condition as well as flies, which an aphis never does. Some 
of the Psyllidie protect themselves from the weather by twisting and 
contorting buds or leaves, but this Poplar-haunting species forms a 
more secure abode by piercing the twigs so as to produce a swelling, 
within which a crowd of these insects in various stages may be found 
closely packed. Towards the autumn the galls will be deserted. It is 
not known at present how these insects pass the winter. The same 
applications are of utility which are successful in the destruction of 
kindred aphides. 
Pansies Falling (.1/. ./. F.). —We do not think the injury to the 
stems Some distance below the surface is caused by slugs ; nor are we
